Local considerations in Rhondda
Surveys in Rhondda also cover the surrounding CF42 district and towns such as Aberdare and Pontypridd. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of Mid Glamorgan fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
For older stone and early brick properties in Rhondda, we look at a wood fibre and lime build-up first.

Wales: planning and regulations
We check Rhondda addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
What finish goes over wood fibre?
A lime-based or mineral render designed for the system, applied over a reinforcing base coat. Lime finishes give the softer, slightly irregular texture that suits cottages and older terraces.

Wood fibre EWI in Rhondda: questions
Is wood fibre insulation fireproof?
No — it's a timber product. It chars rather than flaming readily, but it is combustible, so it's used on low-rise buildings within a tested system and never where non-combustible materials are required.
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Is wood fibre worth the extra cost?
On older solid walls the main benefit is moisture safety rather than raw U-value. If the wall needs to breathe, the cheaper option can cost more later.
Do you cover Rhondda?
Yes — we survey and quote wood fibre external wall insulation in Rhondda (CF42) and nearby Aberdare, Pontypridd and Merthyr Tydfil, with a fixed written price before any work starts.
